How/where to find the overflow hose?
Where is the overflow hose / where can I get access to it to purge? After a bit of research, the discussions I am finding of "overflow hose" refer to the engine coolant system, not the fuel supply.

I used compressed air and a blower fitting and blew air thru mine. Unfortunately that was not the issue with my P0441 CEL

When you open the fuel cap you will see 2 small holes. When gas is over filled, fuel gets into those holes. the theory is with enough over fills and dirt will clog the over flow hoses and develop a fault in the evap system ergo improper flow.

I used one of those canisters of compressed air (the kind you use to dust off your computer keyboard) and cleared out the the two holes leading to the overflow purge lines.
This is a pretty accurate description of what it should sound like when overflow lines are cleared:
Sounds like air whooshing through a metallic pipe.
Reset/cleared the P0441 and P0446 CEL / DTCs and they haven't come back yet. I suspect (hope) this was the source of the CEL / DTCs because I very recently topped off my gas tank, then got the P0441 + P0446.
Thanks all!

P0441 code
Hey you mentioned blowing out a line if you happened to overfill the tank. I’ve tried to check on all the issues but don’t have any luck. Can you maybe give me a point in the direction of where this hose is that I need to blow out? Thanks!!
